IOP Conference Series Materials Science and Engineering · 2019

Key Findings

01Anaerobic closed lagoon was identified as the optimal digester type for industrial wastewaters.
02Water scrubber was determined to be the most suitable biogas upgrading technology.
03A yearly profit of USD 13,700,000 was estimated from selling 279 nm³ of purified biogas.

Application

Design takeaway

Design centralized biogas facilities that integrate multiple waste sources and optimize technology choices (digester and upgrading) to maximize economic returns and environmental benefits.

How to apply

Conduct a feasibility study for a centralized biogas plant by analyzing available industrial waste streams, modeling different digester and upgrading technologies, and optimizing for profit.

Project actions

01Clearly define the scope of waste sources and potential biogas applications for your design project.
02Research the technical specifications and cost-effectiveness of different biogas digester and upgrading technologies.

Method & Evidence

AimWhat is the optimal configuration for a centralized biogas production system within an Eco-Industrial Park to maximize profit from diverse industrial waste streams?

MethodMathematical Modelling and Optimization

ProcedureA superstructure model was developed to represent an Eco-Industrial Park's biogas production system, including multiple sources, digesters, upgrading units, and demand points. The model incorporated parameters like COD, C/N ratio, temperature, methane loss, CO2 removal efficiency, electricity costs, and capital costs. The General Algebraic Modelling System (GAMS) software was used to solve the optimization problem with the objective of maximizing profit.

ContextIndustrial waste management and biogas production within an Eco-Industrial Park setting.

Variables

IV["Types and characteristics of industrial waste streams (e.g., COD, C/N ratio)","Selection of digester technology","Selection of biogas upgrading technology"]

DV["Profit generation from biogas sales","Quantity of purified biogas produced"]

CV["Temperature","Methane loss percentage","CO2 removal efficiency","Electricity cost","Capital cost of equipment"]

Strengths & Limitations

Strengths

+Comprehensive modeling approach considering multiple variables.
+Focus on economic optimization within an Eco-Industrial Park framework.

Limitations

The cost of setting up a centralized system and the logistics of collecting waste from multiple sources can be significant challenges.

Reliability & validity

The validity of the findings relies on the accuracy of the input parameters and the optimization algorithm used in GAMS. Reliability would be enhanced by validating the model with real-world operational data from a similar system.

Think critically

How might the 'ideal' technology choices change if the primary goal was waste reduction rather than profit maximization?

Design Principles

"Waste streams are valuable resources; optimize their conversion through integrated systems and appropriate technology selection for maximum economic and environmental benefit."

This approach transforms waste liabilities into revenue streams, aligning with circular economy principles. By strategically selecting digester and upgrading technologies based on specific waste characteristics, businesses can achieve substantial economic gains while simultaneously mitigating environmental pollution.

What This Means for Your Design

By mixing different types of waste from various factories and using the right equipment, you can make a lot of money from making biogas, while also cleaning up the environment.

How to use in your project

1.Use this study to justify the selection of specific waste streams and technologies in your design project's resource management section.
2.Cite this research when discussing the economic and environmental benefits of integrated waste-to-energy systems.
